Mentor has announced significant advances in the Analog FastSPICE Platform with the introduction of Analog FastSPICE eXTreme technology for nanometer-scale verification of large, post-layout analog designs.

Analog FastSPICE eXTreme includes revolutionary technology that can substantially boost simulation performance, while helping maintain the foundry-certified accuracy required for nanometer-scale analog verification.

Analog FastSPICE eXTreme is especially valuable for analog designs containing high levels of parasitic complexity and contact resistance, both of which grow increasingly problematic as process geometries continue to shrink. Initial customer benchmarks show a simulation performance boost of ten times compared to Mentor’s previous-generation  Analog FastSPICE offering.

Randy Caplan, Executive Vice President for Silicon Creations, said: “As a provider of world-class silicon intellectual property for high-performance clocking such as PLLs, and low-power/high-speed data interfaces such as SerDes, our designs are included in the most advanced systems-on-chip and therefore must target the latest FinFET geometries down to 3nm. Therefore, it is imperative we are able to simulate FinFET designs quickly and accurately to meet our aggressive schedules.

“We participated in the early access program for the Analog FastSPICE eXTreme technology using several large post-layout designs, and have seen up to 10X speed-up while maintaining SPICE-level accuracy. We look forward to using Analog FastSPICE eXTreme to verify our fully extracted designs, enabling first silicon success by achieving our performance and high yield targets.”

Mentor’s Analog FastSPICE Platform provides rapid circuit verification for nanometer analog, radio frequency (RF), mixed-signal, memory, and custom digital circuits. Foundry certified to 5nm and essential to the design of many of the most successful analog integrated circuits (ICs) in the world, the platform delivers nanometer-scale SPICE accuracy two times faster than parallel SPICE simulators.

Available to current Analog FastSPICE customers at no additional cost, the new Analog FastSPICE eXTreme technology is designed to deliver additional performance benefits for large, post-layout analog designs. Analog FastSPICE eXTreme features innovative resistor-capacitor (RC) circuit reduction algorithms, significant performance improvements to the Analog FastSPICE core SPICE matrix solver, and comprehensive, full-spectrum device noise analysis capabilities designed to enable silicon-accurate simulation.

Mahesh Tirupattur, Executive Vice President for Analog Bits, added: “Analog Bits is the leading provider of a broad portfolio of mixed-signal IP such as low-power SerDes, phase-locked loops, sensors and I/O’s in advanced FinFET processes down to 3nm. We have had a long-standing relationship with Mentor and the Analog FastSPICE Platform, and have participated in the AFS eXTreme early access program.

“We have stringent accuracy requirements for our low-power integrated clocking and interconnect IP technology that demand inclusion of post-layout parasitics for FinFET designs to more accurately represent the true analog circuit response. Analog FastSPICE eXTreme technology provides 6X performance improvement while maintaining SPICE accuracy for nanometer analog verification. Mentor and Analog FastSPICE continue to deliver the innovative SPICE technology that we need for designs of today and in the future.”

Analog FastSPICE eXTreme complements Mentor’s Symphony Mixed-Signal Platform, which leverages the Analog FastSPICE circuit simulator and offers fast and accurate mixed-signal verification with industry-standard HDL simulators. The Symphony platform supports verification of complex, nanometer-scale mixed-signal ICs with an intuitive use model, powerful debugging capabilities and configuration support.

“As analogue, mixed-signal, and RF designs continue to advance into deep nanometer nodes, designers worldwide are demanding that circuit simulation performance improves significantly without compromising accuracy in the advanced nodes," said Ravi Subramanian, Ph.D., Senior Vice President, IC Verification Solutions for Mentor. “Our circuit simulation R&D team has been continuously innovating as we tackle every new challenge at advanced nodes, and we are delighted to introduce Analog FastSPICE eXTreme as the next big chapter in our evolution.”

Mentor’s current Analog FastSPICE customers can access Analog FastSPICE eXTreme at no additional cost.
